Immunotherapy has rapidly advanced the field of medicine and has saved countless lives. The approach is much different than using an external chemical, such as in the case of chemotherapy. Immunotherapy leverages the body’s own immune system to recognize and attack foreign pathogens, specifically cancer. While there are many versions of immunotherapy, one rising star among them is known as Chimeric Antigen Receptor (CAR) T cell therapy. This therapy (usually) takes a patient’s own cells in the blood to generate engineered immune or T cells to fight the tumor. T cells are a critical immune cell population responsible for killing or lysing infected cells. In the case of CAR T cell therapy, the T cells from the patient are engineered to recognize receptors on the tumor. The CAR T-cells are then triggered to release different proteins and lyse the tumor cells. This type of therapy has revolutionized the way we treat patients with hematopoietic malignancies or blood cancers.
